ADJUSTABLE SANITARY FOUhT'EAlH-CU? ATESLGHMENT DENTAL CUSPIDOBS.

Application filed. June 6, .5

This invention relates to in'iprovements in attachment for dentalspittoons or cuspidors of the fountain type, and it consists in certainpeculiarities of the construction, novel arrangement and. combination ofthe various parts thereof as will be hereinafter more fully describedand specifically claimed.

The main object of the invention is to horizontally adjustable attaclrment for dental cuspidors of the above named class, whether the same ismounted on a pedestal, or stand, a dental chair, or on the wall of aroom, whereby a fountain of water h preference. in the form of abubbling or overflowing cup, may he so positioned over the lap by a.patient while occupying the dental chair, or by the operating dentist,that the fountain or cup can be readily reached for use in rinsing themouth or for drinking purposes, without undue distortion of the body ofthe patient, and can then bemanually moved. out of the way, orautomatically retracted to its norn'ial or initial position.

Another object is to so construct and arrange the parts of theattachment, that it can be readily applied to any of the standard makesof dental cuspidors of the fountain type, without material alterationtherein, so as to cooperate with the water supply of the cuspidor infurnishing convenient, handy and sanitary means for supplying a.fountain of water at a point near the cuspidor or at a reasonabledistance therefrom? Still another object is to provide means forauton'iatically turning on the supply of water to the bubbling cup of heattachment in the operation of the extension of the same, and forautomatically cutting off such supply when the parts are retracted orreturned to their normal positions.

Numerous other advantages and objects of the invention will becomeobvious from the following description and explanation.

Corresponding numerals of reference r 1 fer to like parts throughout thedifierent views of the drawings.

In the present instance, I have shown my attachment in connection with apedestal supported fountain cuspidor, and in the following descriptionand explanation will so describe and explain it. yet it will be readdyunderstood by those skilled in the art to which the invention pertains,that the cur;-. pidor may be supported by a stand, a wall support. or bya suitable support attached to the dental chair, and for this reason. lde sire to be understood not limiting myself in any manner as to theconstruction of the support for the cuspidor bowl.

Referring now to Fig. 1 of the drawing, the reference number. 1.0designates a pedes tal on the upper end which is mounted an arm 11 ofthe ordinary or any preferred design, which carries on one of its ends acuspidor bowl 112 and on its other end a finger howl 13. The 11, as wellas the pedestal 10., is hollow and has extended therethrounh, as is wellknown, outlet pipes or conduits which communicate at their upper endswith said bowls, and lead at their other ends, to

any suitable point for discharge.

The pedestal and arm also has extended therethrough in a well-known way,a water supply pipe which is connected to a. fixture i l of any wellknown construction,

the the which fixture vertically inountec. on arm 11 and extendsupwardly between bowls l2 and 13, and is provided near upper end withone or more faucets l5 which are located so as to di charge water in thecuspidor bowl. The fixture 1 is provided with shut-oil or controllingvalve 16 near its juncture with the arm 11 and on its up per portionwith a valve casing 17, from which the faucet or faucets 15 for the bowl12 are extended. This valve casing is also provided with a valve 18 forcontrolling the flow of water through the faucet or faucets 15 and hasextended through its upper end a nozzle or pipe 19 to which the ordinarygooseneck shaped faucet or outlet pipe for drinking water is fitted atits lower end. So far as described, the construction ot the parts namedis or" the ordinary or wellknown kind.

In mounting lny attachment on the iix ture 14L, the faucet or outletpipe for drinking water is removed from the pipe 19 at the upper end ofthe valve casing 17, and in lieu thereof the lower end of the uprightsupply tube 20 of my attachment is screwed onto the pipe 19 as shown ligz 2, or the same may be otherwise suitably mounted on the upperportion of the valve casing); 1'? and in communication therewith.

As is clearly shown in Fig. 2 of the drawings, the attachment consistsof the upright supply tube 20 having: a number of transverse openingsextended diametrically anl lmrisontally thcrethrough one above theother. The lowermost pair of these openings has fitted therein a. tube21, the uppermost one a tube 22, and the intermediate pair of saidopenings the tube 23, each of which is closed at one of its ends by ascrew cap 24-, each of which caps is by preterenee ornamented with aglobular proiection 25 located on its outer surface. Near each of theirends the tubes 21 to 23 inclusive are conn cted together and braced bymeans of vertically disposed bars 26 which bars are provided at suitabledistances apart with openings of the iropcr size to it snugly aroundtheir respective tubes. The bar 26 at the outer ends of the horizontaltubes is provided in its upper portion with a transverse opening 2'?through which is extended a short tube 28 which communicates at one ofits ends with the upper portion of the supply tube 20 and at its otherend with th uppermost tube 22 near the outer end of the latter. Thislast mentioned tube, as well as the tube 21, has its'cavity ad its screwwith a valve 31 to control the How of water through said pipe.Telescopicaliy fitted in the inner end of each of the tubes and 23, arethe inner ends of tubes 32, and 3 1- respectively, which are connectedat their opposite ends to an upright tube 3:; which is closed at itslower end preferably by means of a screw cap 36 of an ornamental design.

By reference to Fig. 2 it will be seen that he tubes and 33 communicatewith the aviiy of the tube 35, while the tube 34: does lot havecommunication with said tube, but 5 fixed to the wall thereof in anysuitable manner.

The tube 35 is provided on its wall opposit-e the adjacent ends of thetubes 32 and 33, with a handle brach to be used for 1/ OD moving thetubes 32 to 84 inclusive back and "forth with respect to the fixed tubes21 to 23 inclusive. Mounted on the upper portion of the upright tube 35is an overflow bowl 37 of glass or any other suitable material. Withinthis bowl and mounted on top of the tube 35 is a cup 38 of any suitablematerial which ha extended centrally through its lower portion a tube 39which extends into the tube 35 and from thence into the uppermost tube33 of the slidahle tubes. It will l e understood that the parts of tieattachment which are exposed to water are titted in any well-known wayso as to prevent leakage. In its periphery between the bowl 37 and cup38 the tube 35' is provided with afnuinber of openings 4!) to permit thepassage of water from the bowl 3? into the tube 35'froin whence it willescape through the tube 82 and an outet tube d1, Which may lead to anysuitable point for. discharge.

Each o 'f the tubes 21, and 22, has threaded on its end a ring nut orpacking gland 1-2 which nuts surround the tubes 32 and 33. yet in such amanner as to permit o't sliding movement of the latter. Between theglands 4:2 the tubes on which they are coated packing- 43 of a suitablemounted is l kind. The inner end of the tul'ie pro- 'i led with aninturned projection 41.4. which is adapted to operate in aslot 45 in thelower portion of the tube 34 and to engage a portion 46 ot the tube atits inner end to restrict the out-ward movement of the slidable tubeswith. respect to the fixed tubes of the at achment.

@ecured at one of its ends to a projection 47 on die cap 2 which closesthe outer end of the tube 2. is a spiral spring 48 w rich has other endsecured to a suitable projection 49 within the end the tube 34 adjacentthe cup bearing tube.

Pivoted near one of its ends on a suitable bracket 50 with which thewall of the waste water tube 35 or cup bearing tube is provided near theend of the tube 34: adjacent thereto, is a locking-bar 51 which isadapted to engage the inner end of the tube as is clearly shown in 3 ofthe drawings, and thus prevent the tubes 32 to 3t inclusive beingretracted within the tul L1 to 23 inclusive in connection with whichthey are mounted for telescopic engagemeni by the action or tension ofthe spring 48, or accidentally when said spring is not employcd. Thescrew cap 24 which closes the out .3 end of the tube22 is provided onits inner surface with a cone-shaped plug 52 which employed to close theinner end of the tube 33 when the cup hearing or waste water tube isretracted to the normal position of the parts of the attachment. linorder that water may enter the tube 33 through the pipe section 28 whichleads from the supply tube 20 on a slight move ment outwardly of thetube 33 the outer end of the cavity in the tube 22 is enlarged as at 29,see Fig. 2 of the'drawing.

For the purpose of permitting the exhaust or waste water to bedischarged from the outer end of the tube 21 and from thence through theoutlet tube 41, the outer end of the cavity in the tube 21 is alsoenlarged as at 29, see Fig. 2 of the drawings.

l rom the foregoing, and by reference to 2. it will be understood thatthe pipe section 28, and the tubes 22 33 and 39, con stitute the conduitfor supplying water to the cup 38 from which it will overflow into thebowl 37 and pass therefrom through the openings 4.0 into the cup hearingor waste water tube from whence it will pass through the tubes 32, 21and 41 which constitute the'outlet conduit of the attachment of theabove described construction.

In Fig. 6 I have shown a modification in the construction of theattachment which in the employment of an upright water supply tube 53which is adapted for engagement and communication with the upper end ofthe nozzle or pipe 19 of the valve casing 17 of the water fixture 14: inveryinuch the same manner as the tube 20 oi the first above describedconstruction and above set forth.

The supply tube 53 of the modification now under consideration. may havemounted on its upper end the lower end of the faucet or outlet pipe 30for drinking water, which is, as in the other construction, providedjust above its juncture with the tube 53 with a valve to control theflow of water through the said pipe. The tube 53is provided in itswallabout midway between its ends with an opening 5% in which is fittedagainst leakage a short pipe section 55 which has therein a. centrallydisposed coneshaped plug 56 which is spaced from the inner surface ofthe wall of the member 55 and has openings 57 in its support betweensaid plug and the member 55 for the passage end of the latter.

of water. Fitted in the outer end of the number or secured theretoagainst leale age is a horizontally disposed tube 58 which forms a partof the water supply conduit from the tube 53 to the cup 38 of themodified form of the attachment now being do scribed.

Fitted around a portion of the tube 3 and the u oer )art of the nozzleor nine l9 4 l l l J is a sleeve 59 which has communicatie witl itslower portion an outlet pipe which nia-y lead to any suitable point fordischarge. Surrounding the pipe section 55 and tube 58 is another tube61 of lar diameter than the tube 58, which has one of its ends fitted inan opening 62 in the wall of the sleeve 59 and extends in parallelismwith the tube 58 to about the outer Located in the tube 61 fortelescopic movement therewith is a tube 62 which communicates at itsouter end with a cup hearing or waste water tube 63 which is verticallymounted on the tube 552 and may be equipped with handled bracket 36 asin the other construction.

Slidably located in the outer end of the tube 58 is a tube 6d which isextended into the tube 62 and has communication with the cup 38 throughan elbow pipe 39 which is vertically supported in the tube 63 by ahorizontally disposed perforated frame 65 secured to the inner surfaceof the cup bearing tube; This last named tube has mounted on its upperportion the bowl or basin 37 and is provided between said basin and thecup 38 with perforations to for the passage of the overflow water fromsaid cup. The outer end of the tube 61 has mounted thereon aring nut orpacking gland 66 which surrounds the tube 62 in such a way as to permitslidable movement of the tube 62 through said ring and with respect tothe tube 61. 3

Located between the gland or ring 66 and the adjacent end of the tube 61is gasket or packing ring; 67 of any suitable kind used to preventleakage. That end of the tube 58 adjacent the supplytube 53 has itscavity enlarged as 29 for the same purpose as the enlargement 29 in thetube 22 of the first above described construction. By the abovedescribed construction of the modified form of the attachment it isevi-- dent that the pipe section 55, tubes 58, 64%, and constitute thewater supply conduit from the supply tube 53 to the cup 38 and that thecup hearing or waste water tube 63 and the tubes 60, 61 and 62constitute the conduit for the outlet of water from the cup 38 andoverflow basin 37.

On its lower portion near its outer end, tube 61 has a depending andlaterally apertured bracket 68 through which is slidably extended ahorizontally disposed stop rod 69 which has on its inner end a knob 70 Hll to contact with the bracket 68 when the cup bearing tube 68 isadjusted to its outermost position, so as to prevent disconnection ofthe tubes 82 and 64 from the tubes 61 and 58 respectively. The outer endof the rod 69 is suitably connector to the lower portion of the cupbearing tube 68 on its surface opposite it handle bracket. The sleeve 59which surrounds the supply tube 53 and a portion of the pipe 19 is heldspaced relation around said parts by means of suitable collars 71 andach 01 which may be e uipped with a pack 8 and a suitable gland74lthepefor.

In the constructions above described, the attachment is constructed foradjustment in a horizontal plane only. but in the modified constructionshown in Fig. '7 and which will now be described, I have shown means notonly for the adjustment '5 the cup 88 and its bowl in ahorizontal plane,but also for pivotal adjustment therefor.

The present modification consists of an upright water supply tul e 75which is adapt ed for connection at its lower end with the nozzle 19 oroutlet pipe from the upper end of the valve casing 17 or" the waterfixture 14 and may be equipped at its upper end with an outlet pipe orfaucet for drinking water, which faucet or pipe may have a controllingvalve 31 as in the other described constructions.

Surrounding the upper portion of the supply tube 7 5 is a sleeve 76which has on its wall a pair of spaced apertured lugs 77 and below thelowermost of said lugs a tubu lar member 78 secured at one of its endsin any suitable manner to the tube 75 and provided at its other end witha ball or knob '79 for ornament. This tubular member 78 has extendedfrom its lower portion a tubular section 80 which is located near theouter end thereof and between said tubular section 80 and the wall ofthe tube 75, the membar 78 has connected thereto one end of an outletpipe 81 which may lead to any suitable point for discharge. Extended atits upper end through suitable registering openings in the sleeve 76 andsupply tube 75 is an elbow pipe 82 which extends through a suitableopening in the upper surface of the extension 7 8 and thence through thetubular s ction 80 a slight distance below the lower end of saidsection.

Vertically located in the apertures of the lugs 77 is a. 'pintle 83 onwhich is loosely mounted between the lugs 77 a pair of collars 84- each01 which has pivotally connected thereto one end of an arm or lever 85of a bracket, which is designated as a whole by the numeral 86 and is inthe form or well known construction of a lazy-tongs. This bracket orlazy-tongs is pivotally connected at its end opposite the pintle'83 to acollar 87 which surrounds and supports the upright cup bearing or wastewater tube 88 oi the modified form now under consideration. This cupbearing tube may be provided as in the other constructions, with ahandle bracket 36 for the manipulation of the device, and has mounted onits upper portion a bowl 87, and within said bowl and on its top a cup38 as in the other constructions- 1 Between the lower end of the cup 38and the 'bowlthe tube 88 is provided with perforations 4:0 for theoverflow water from the cup 88 and from said bowl. Extended downwardlythrough the cup 38 and into the tube 88 to near its lower end is atube89 which has communicating with its lower portion an elbow pipe 90 whichis extended laterally through an opening in the wall of the tube 88 andthence downwardly and transversely through a tubular member 91 securedat one of its ends to the wall of the tube 88 near its lower end andhaving at its other end a knob 92 or other suitable ornament. The member91 is provided on its lower portion with al downwardly extended pipesection 98, and it will be observed by reference to Fig.

7 that the elbow pipe 90 is extended at its lower end beyond the lowerend of said pipe section. Connecting the lower end of the elbow pipesection 82, which leads firom the supply tube 7 5, to the lower end ofthe el bow pipe section 90 is a flexible tube 94: which may be of anysuitable length. This flexible connection 94L is surrounded by aflexible tubular connection which is of larger diameter than theconnection 9d and has one of its ends secured to the tubular extensionor member 80 and its other end to the tubular member 93 of the part 91on the movable or cup bearing tube.

%y the foregoing arrangement and construction of the. parts of themodified form of the attachment now under consideration, it is manifestthat the elbow pipe section 82 leading from the supply tube 75, theflexi ble connectio 94:, the elbow pipe section 90 leading into themovable tube 88, and the pipe 89 communicating at its upper end with thecup 38 form the conduit tor the supply of water from the tube 75 to saidcup.

It is further apparent that the cup carrying tube 88, the extension 91thereon, the flexible connection 95, the tubular extension 78, and thepipe 81 leading from the latter member, form or constitute the outletconduit from said cup and the overflow basin 37 mounted below and aroundthe same. By means of the last described extensible connection betweenthe supply tube and the movable tube or the attachment, it is evidentthat the movable tube carrying the cup on its upper end. can not only beadjusted horizontallywith respect to the supply tube, but can also beturned sidewise with respect thereto.

To more securely support the arms or levers 85 of the lazy-tongs 86, Imay secure on each side or face of the tongs 86 a pair of parallel guiderails 96 having one or" their ends fastened to the collar 87 and theirother ends extended horizontally a suitable distance towards the pin-tle83 when it is apparent that the pivots 97 of the arms 85 of thelazy-tongs will ride on and between the said rails.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. In an attachment of the classdescribed, the combination with a. water-supplytube adapted forcommunication with a supply of water, of another tube mounted thereonfor horizontal adjustment with respect thereto, a cup mounted on saidadjustable tube, hori zontally extensible means for the passage of waterconnecting the supply tube to said cup, and means for automaticallyclosing said water passage on the retraction of the movable tube.

2. In an attachment of the class described, the combination with awater-supply-tube adapted for communication with a supply of water, ofanother tube mounted thereon for horizontal adjustment with respectthereto, a cup mounted on said adjustable tube, extensible means for thepassage of water connecting the supply tube to said cup, and means forautomatically opening said water pass-age on the initial horizontaln'iovement of the movable tube from the supply tube.

8. In an attachment of the class described, the combination with anupright water-sup ply-tube adapted for communication at its lowerportion with a supply of water, of a wastewa ter-tube mounted inparallelism with the supply-tube, a bowl mounted on saidwaste-water-tube in communication therewith, a cup on said tube withinsaid bowl, an extensible water-supply conduit communicatingly connectingthe supplytube and said cup, means at one end of said conduit forautomatically closing the same on the retraction of the waste-water-tubeto its normal position, and an extensible wateroutlet conduit supportedby the supply tube and communicating at one of its ends with thewaste-water-tube.

4. In an attachment of the class described, the combination with anupright water-supply-tube adapted for communication at one of its endswith a supply of water, of a waste-water-tube mounted in parallelismwith the supply-tube, a bowl mounted on said waste-water-tube incommunication therewith, a cup on said tube within said bowl, anextensible wa ter-supply-conduit communicatingly connecting thesupply-tube and said cup, means at one end of said conduit forautomatically closing the same on the retraction o1 the waste-water-tubeto its normal position and for automatically opening said conduit whensaid waste-water-tube is moved from the supply-tube, and an extensiblewater outlet conduit supported by the supply-tube and communicating atone of its ends with the waste-warter-tube.
